BURNER FOR HEATING AND ILLUIVIINATI'NG PURPOSES.

Specification of Letters Patent.

Patented May 7, 1907.

Application filed June 5,1905. Serial No. 263,841.

- poses, of which the following is a specificatlon.

; This invention has reference to improvements in the construction of burners for heating and illuminating purposes whereby a more intimate mixture of air and gas is obtained resulting in a flame of veryhigh calorific and illuminating value.

The main features of my improvements consist in providing in a burner of the Bunsen type a nozzle having a number of small spiral ways or passages for the'discharge of the volatilized oil or gas the orifices being placed round or near the top or end of a hollow ring or truncated cone together with a small fan placed above or in front of the orifices and revolved by the impact of the issuing gas.

I will now refer to the accompanying drawings to illustrate my invention.

Figure 1 is a side elevation of my burner. Fig. 2 is an end elevation of same. Fig. 3 is a section through the line AB Fig. 1, while, Fig. 4 is a detail showing the hollow nut which forms part of the nozzle.

1 is a pipe leading from an oil or gas supply under pressure.

2 represents a volatilizing coil of any suit.- able kind but in some cases this may be dis pensed with as hereinafter explained.

3 is a fan which freely rotates on the shaft or standard 4 secured at the base of the burner. I

The nozzle denoted in a general way by 5 includes a hollow nut 6 having an approximately cone shaped opening at the center and provided with a screw thread? which engages with a thread at 8 on the sleeve 8 constituting part of the nozzle 5. The said nut 6 has cut or machined on it at one end a series of spiral ways or grooves 9, leaving when screwed up openings or orifices at 10.

11 represents an annular chamber open to the spiral ways and formed by a groove 12 round the body of the nut 6 and a groove 13 on the outer portion of the burner nozzle.

14 are projections on the nut for screwing it into place while 15 is a regulating valve of any suitable pattern.

The oil is forced through the pipe 1 and is volatilized on passing through the coil 2. The gas thus formed passes up the branches of the burner and out the orifices 10, the

spiral ways 9 together with the motion of the fan 3 causing a cyclonic action to be set up in the mixed air and gas.

It will be obvious that I employ a fan in advance of the burner and that I rotate this fan by jets of gas impinging thereagainst and issuing from a series of annularly disposed 'outlets in the burner. The axis of motion of the fan is substantially coincident with the cen-v ter of these outlets so that compactness is assured.

In some cases I may heat the air before permitting it to mix with the volatilized oil or gas and where crude oil is employed I may dispense with the heating coil or plate and obtain the necessary volatilization by mixing steam with the oil.

In using the burner for illuminating purposes it is desirable to employ a high pressure to obviate any flickering which too low a pressure is apt to cause. I may also use the flame in combination with a suitable incandescible body.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a burner, the combination of a sleeve having an interior annular groove, and a nut fitted in the sleeve and having a comple mental annular groove and spiral ways, said spiral Ways being surrounded by the sleeve to form at the outer end of said burner an annularly arranged series of gas outlets.
